mouth. Both fingers are wide, blunt, and untoothed. but 

 bearing on each inner edge a single central rounded pro- 

 jection. 



Palps are absent. 



Ovigers possess ten joints and a claw. First joint is 

 short, second, third, and fourth are progressively longer. 

 Fifth joint is long cui'ved and slender, distally expanded 

 with a peg like process at this end, the process being 

 crowned with a number of short seta?. Sixth joint is short, 

 and the seventh, eighth, ninth, and tenth are progressively 

 shorter. The last four joints are provided with a few bent 

 compound spines arranged in a single row. The temiinal 

 claw is long and sharp and is ornamented with fine teeth 

 on the distal half of its inner edge and on the distal third 

 of its outer edge. 



Legs. — The first and third coxae are short and sub- 

 equal. The second is as long as the other two together and 

 is distally expanded. The femur is a long joint a little 

 longer than the combined coxae. The first tibia is a little 

 shorter and expands distally. The second tibia is a little 

 longer than the femur. The femur, first tibia, and second 

 tibia are approximately divided into thirds by shallow 

 transverse constrictions. All these joints are minutely 

 spinous. The tarsus is short with a very small dorsal spine 

 and a bunch of closely crowded ventral spines. The pro- 

 j>odu3 is very stout, minutely spinous. On the sole, 

 proximally, there are some four or five well developed 

 spines. The distal half of the sole has smaller spines. The 

 claw is large, strong, and curved, and is equal to moi^ 

 than two-thirds the length of the propodus.
